Appncanon ined March 2o, 1893. sennoniaseo. oto modela To all whom it may concern/.-

Beit known that I, WILLIAM G. CLAHASEY, residing in Lenox, Berkshire county, Massachusetts, have invented certain new and usef ul Improvements in Horseshoes, of which the following is a specification.

My invention relates to horse-shoes, and more particularly to that class of'horse-shoes which are commonlyterrned two-part or combination shoes, and it hasforitsobject to provide an improved combination shoe in which the parts can be easily separated or securely held in position, and in which `the'calks may be readily removed or replaced, and to these ends myinvention consists in. a shoe embodying the various features of construction and arrangement of parts, substantially as hereinafter more particularly set forth.

Referring to the annexed drawings, wherein I haveillustrated a preferred embodiment of my invention, Figure 1 is a perspective view of the inner permanent shoe. Fig. 2vis a perspective View of the outer or removable shoe. Fig. 3 is a longitudinal Vertical section showing the combinedshoe. Fig. 4 is a vertical section of the same through the heel calks.u Figs. 5 and 6 are perspective views of portions of a calklessshoe; and Figs. 7 and 8 are similar views of rportions of a modified calkless shoe.

The permanent shoe A, is provided-with. the usual nail-holes d, and preferably with an upturned portion a by means of which it may be tightly secured to the horses hoof in the usual manner. It is also provided with an inwardly projecting portion B, having a screwthreaded opening b. The ends of the shoe are turned u p to form locks or clamps for the purpose of aiding in securing the removable shoe in place, and in Figs. 1 and3, I have shown the end C turned up to form a clamp,having a recess c for the reception of the ends of the removable shoe: While this form of clamp'is desirable in many instances, it is evident that it can be simply turned up at an angle, as shown at C', Fig. 8. `The shoe is also provided with recessed portionsD into which the cal-ks lit when Vthey are used.

The outer or removable shoe E is shown as.

consisting substantially of a fiat shoe, the ends F of which are arranged to tit within the clamps C of the permanent shoe, and these ends may be chamfered or reduced, as shown at f; or when the shoe is not too thick, the plain ends of the shoe may fit in the recesses c of the clamp.

Projecting inward from the outer shoe is a portion G corresponding to the portion B of the permanent shoe, and this is also provided with an opening g for the reception of thescrew I-I and this opening is preferably countersunk, as shown in Figi 3, so that the head of the screw when in proper position, will be flush with the outer or wearing surface of the shoe. The removable shoe is also provided with openings I, near its ends, and an opening .I near its forward portion, and the walls ot these openings are tapered, as shown in Figs. 3 and 4. The calks K tit in these openings, being made tapered so as to fit closely, while the enlarged o r thickened ends of the calks rest in the recesses D, in the permanent shoe.

When it is desiredto use a shoe without the toe and heel calks, it may be formed as indicated in Figs. 5 and 6, in which both the permanent and removable shoes are recessed to receive a locking block L, or the block L may be fitted permanently to one portion of `the shoe.

In using the shoe, it will be apparent that the permanent portion is secured to the horses hoof, and the calks K being slipped into position in the removable shoe, the ends F are `inserted in the recessesc of the clamp C, and

through the openings in the removable shoe and entering the recesses D in the permanent shoe, form a secure lock,preventing any sidewise or endwise movement of the parts with relation to each other.

When the calks are used, a clamp C substantially as shown in Fig. l, may be used; but 'if it is desired to use the shoe without the calks, the clamp may be made substantially aSindicated in Fig. 8, so that it willnot project beyond the outside level of the shoe. Sometimes, especially when itis desired to use racing shoes, the permaneutgshoe may be made as indicated at M, Fig. 7; that is, the ends may be beveled, as at ym and in this case, the outside or removable shoe N would have its ends provided with a clamp n which would embrace the beveled ends m, and then when for racing or other purposes, the outside shoe is removed, the animal would have firmly fixed to his foot a practically new and un-` worn, light racing shoe, with a smooth surface.

It is evident that the different forms of clamping devices can be applied to the different shoes. Thus, for instance, the inner shoe, shown in Fig. 1, may have beveled ends, and the outer shoe be provided with a clamp to embrace the ends. It is also evident that the calks may be of different shape or configuration, and may have sharp or blunt edges, and in fact one of them maybe rounded, especially the one used on the inside of the hoof, so that there will be less danger of injury; but these are well-known modications to those skilled in the art. It will fu rtherbe observed that especially when heavy external shoes are used, the calks may be permanently tted to the external shoe, and form a part thereof, while the shoe might be provided with lugs or extensions corresponding to the enlarged portion ot' the'calk, to t the recesses in the inner shoe. Other modifications will suggest themselves to those skilled in the art, which may be made without departing from the spirit of my invention.

The advantages of the use of such a shoe need not be fully set forth,as they will be appreciated by those skilled in the art. It is well known that on icy or slippery roads, it is desirable to use calks and with my arrangement, these can be readily supplied and changed when desirable, and if, as in snowy weather,it is desirable to remove them,it can be accomplished without delay or trouble.

Moreover, if the animal is standing for any length of time, the unused or outer shoe can be removed and the permanent shoe remain, whichislightandrelativelythin,andallowsthe horses hoof to come practically in contact with the ground, so that it will be better preserved. Moreover, as the outer shoe wears, it can bc replaced by another, or others, without the necessity of removing the permanent shoe, which removal is liable to injure the horses hoof.

It will be seen that the parts of the comb'i` nation shoe are securely held together, it being necessary only to set or loosen a single screw to secure or remove parts. The recesses or openings in the parts for the reception of the calks or blocks form additional means ol' -maintaining the parts together under all conditions of strain or use.

What I claim isy In a twopart horse-shoe, the combination with a permanent shoe having clamps at its ends and recesses in its face; of a removable shoe having openings, and calks fitting the openings and extending into the recesses, and means for securing the two parts together; substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
